BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door trim having an insulated member, and more particularly to an automobile door trim having an improved waist appearance.

[0002]

2. Description of the Related Art In recent years, in order to enhance comfort in a vehicle interior, materials of interior parts such as car door trims have been upgraded, or decorative members such as cloths and carpets have been attached to appropriate locations on the interior part surface. The method is heavily used.

FIGS. 4 and 5 are a perspective view and a sectional view, respectively, of a conventional car door trim. A car door trim 1 includes a core 2 formed into a required shape and a surface of the core 2. Door trim main body 4 composed of a skin material 3 integrally attached to the door trim body by vacuum molding or the like, and a decorative portion is further imparted to an appropriate portion of the surface of the door trim main body 4 (from the center to the waist in this example). And an insulated member 5 to be mounted.

[0005] The configuration of the insulated member 5 is shown in FIG.
As shown in FIG. 5, an insulated pad material 5c such as a polyurethane foam is bonded to an insulated core material 5a via a board 5b to an insulated core material 5a, and the surface is further covered with an insulated skin material 5d such as a leather. It is configured.

Further, in order to attach the insulated member 5 to the door trim main body 4, first, the insulated pad material 5c is bonded to the board 5b, and then the peripheral edge of the insulated insulative material 5d is sewn to the board 5b. Then, after bonding the board 5b, in which the inlaying pad material 5c and the inlaying skin material 5d are integrated, to the inlaying core material 5a, a locking claw cut and raised on the inlaying core material 5a (not shown) ) Is inserted and fixed in a mounting hole (not shown) of the core material, the insulated member 5 is attached to the door trim main body 4, and the upper edge terminal of the insulated skin material 5 d is tensioned, and the waist of the door trim 1 is applied. Roll along the flange,
It is adhesively fixed to the inner seal bracket 6.

[0006]

As described above, in the door trim 1 of the type in which the insulated member 5 excellent in cushioning property and decorativeness is installed from the center of the door trim body 4 to the waist, for example, a good cushion is provided. When the insulated pad material 5c is set to a thickness of about 10 mm in order to secure the property, a good cushioning property can be obtained in the central portion of the door trim 1 where the occupant can easily touch, but the middle portion along the waist portion is obtained. In the operation of rolling in the covering material 5d, due to the variation in tension, the intermediate pad material 5c tends to be elastically deformed and non-uniform, causing a waving phenomenon of the waist portion shown in FIG. However, it has been pointed out that it is easy to meander, resulting in remarkable deterioration in appearance.

Conversely, if the thickness of the insulated pad material 5c is set to be small in order to alleviate the influence of variations in tension when the insulated skin material 5d is involved, the door trim is easy to touch by the occupants. There has been a drawback that the cushioning property of the central portion is reduced, a luxury feeling cannot be obtained, and the commercial value is reduced.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an interior part in which an insulated member is installed from the front center to the waist of an automobile interior part. In addition to ensuring good cushioning performance in places where the occupants can easily touch, waviness in the waist and meandering of the waistline are resolved,
It is an object of the present invention to provide an automobile interior part in which the appearance of a waist portion is significantly improved.

[0009]

In order to achieve the above-mentioned object, the present invention provides a door trim body comprising a core material formed into a required shape and a skin material integrally adhered to the surface of the core material. In an automotive door trim having an insulated member mounted from a surface center portion to a waist portion of the door trim main body, the insulated member includes an insulated core member and a front side of the insulated core member. The projection is formed from an insulated pad material and an insulated skin material that are laminated, and a projection that comes in contact with the insulated skin material along the upper end edge of the insulated core material is bent. It is characterized by being formed.

[0010]

As is apparent from the above configuration, since the protrusion is provided along the upper edge of the core material for the inlay, when the skin material for the inlay is wound along the waist portion of the door trim, the middle is used. The contact skin material abuts along the upper edge of the protrusion , and this protrusion has a linear tip.
Since it becomes a hit point and a uniform force acts on the padding material for the inlay, no irregularities are formed on the waist appearance, and the waist line does not meander.

[0011]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a door trim for an automobile according to the present invention.

FIGS. 1 and 2 are a perspective view and a sectional view showing a door trim for a vehicle to which the present invention is applied, and FIG. 3 is a sectional view of the door trim for a vehicle showing a second embodiment of the present invention.

1 and 2, a vehicle door trim 10 to which the present invention is applied generally comprises a door trim main body 11 and an intermediate member 20 mounted from the center of the surface of the door trim main body 11 to the waist. ing.

More specifically, the door trim body 11
Is composed of a core material 12 formed in a required shape, and a skin material 13 integrally attached to the surface side of the core material 12 by vacuum molding or the like. A composite resin material comprising a polypropylene resin and a filler such as wood flour or talc is used in consideration of cost, mechanical strength and the like, and a PVC sheet is used as a skin material.

Next, the configuration of the insulated member 20 is formed along the curved surface of the door trim 10, and the insulated core member 21 such as an iron plate having the function of holding and supporting the shape of the insulated member 20 is provided. Inexpensive padding material 22 such as slab urethane foam supported by core material 21,
And an insulative skin material 23, such as synthetic leather, which covers the surface of the body.

The feature of the present invention is that the inscribed member 20
When the winding material is attached to the door trim 10 and the winding operation is performed on the insulated skin material 23, even if the winding tension varies, the projection 24 becomes a linear front contact point. The center member 20 is capable of enhancing a sharp waistline without a meandering phenomenon.

That is, a projection 24 of about 3 to 4 mm is formed to be bent upward along the upper end edge of the core material 21 for the inscribed member 20.

Next, a description will be given of the operation of forming the protrusion 24 on the core member 21 for inscribing. Since this operation relates to the work of attaching the insulated member 20 to the door trim main body 11, the attachment of the insulated member 20 is performed. A description will be given in relation to work.

First, after the insulated pad material 22 is adhered to the board 25, the insulated skin material 23 is coated from the surface side, and the peripheral edge of the insulated skin material 23 is sewn to the board 25. Perform processing.

Then, a board 25 in which the inlaying pad material 22 and the inlaying skin material 23 are integrated is fixed to the inlaying core material 21 via an adhesive. The centering member 20 is attached from the central portion to the waist portion of the door trim main body 11 by bending and fixing the locking claw 21a cut and raised to the inside of the mounting hole 11a formed in the door trim main body 11, and thereafter, Replacement skin material 23
Is wound around the back side of the door trim main body 11 and is adhesively fixed to the inner seal mounting flange 14.

At this time, since the winding force is applied to the insulative skin material 23 and it is a manual operation, it is inevitable that the tension varies. However, in the present invention, the insulative material protrudes along the upper edge of the insulative core material 21. Since the portion 24 is formed, the insulting skin material 23 abuts on the upper end edge 24a of the protrusion 24, and the protrusion 24 functions as a stopper. Not affected.

Therefore, the variation in tension does not appear as irregularities on the product surface, and the waistline does not meander, and a sharp waistline along the upper edge 24a of the projection 24 can be emphasized, and the waistline can be emphasized. There is an advantage that appearance is remarkably improved.

In the drawing, reference numeral 30 denotes an inner seal mounted on the inner seal mounting flange 14.

If the tip of the projection 24 is subjected to a roll process or a hemming process, it is advantageous in that the inlay skin 23 is not cut off when the inlay skin 23 is wound.

Next, FIG. 3 shows another embodiment of the present invention. In this embodiment, the lip portion 31 of the inner seal 30 is set on the waist line of the door trim 10.

Also in this embodiment, since the projection 24 is formed at the upper end edge of the core member 21 for the insulated member 20, the waist line is covered by the lip 31 of the inner seal 30. Although it is not possible to emphasize a beautiful waist line, conventionally, in this type of door trim, a gap occurs between the lip portion 31 of the inner seal 30 and the waist portion of the door trim 10 due to a variation in tension, resulting in an uneven appearance. According to the present invention, the thickness of the door trim 10 is ensured by the protrusion 24 of the insulative core material 21, so that the gap between the door trim and the lip portion 31 of the inner seal 30 is prevented. Can,
The appearance is improved by the prevention of skidding, and a good feel is obtained.

[0027]

As described above, the vehicle door trim according to the present invention has the following special effects.

(1) When a projecting portion is set along the upper edge of the core material for the insulated member in the insulated member and the skin material for the insulated material is wound on the back surface side of the waist portion, the winding tension varies. Even in this case, the protrusion functions as a stopper, and the product surface does not have any irregularities, and the waving phenomenon of the waist, which had occurred conventionally, can be prevented, so a sharp waist line is obtained and the appearance near the waist part is improved This has the effect of significantly improving the product value.

(2) Since there is no influence from the variation of the winding tension in the winding operation of the insulated member, the thickness of the insulated pad material can be set to be large, and a good feel and cushioning performance can be obtained. It has the effect of emphasizing the sense of quality.
